T0 rZl whom 712'; may concern.-

Be it known the-t1, WlL-LIAM J. MURRAY, a citizen of the United States,residing at Denver, in the county of Denver and State of 5 Colorado,have invented new and useful Improvements in Coal-Slack Levelin andTamping Appliances, of which the fol owing is a specification.

This invention relates to an appliance for leveling and tampingcoal-slack in ovens of the so-called beehive type. V.

The nature of the invention will be readily comprehended, referencebeing had to the following detailed description of the con struction andoperation and to the accom panying drawings,illustrating the appliancein its'preferred form of embodiment, it being understood that variouschanges and modif cations may be made therein without exceed- .ingthescope of the invention defined by the concluding claims,

In the drawings, Figure 1 is an elevation, partly in section, of acoal-slack leveling and camping appliance embodying the invention.

5 Fig. 2 is an enlarged detail view of certain combined parts or membersof the appliance in one position. Fig. 3' is a view similar to Fig, 2with the parts in another position. Figs. 4, 5, and 6 are furtherenlarged detail Fig' 7 is a cross-sectional View of one of thetampingarms 23..

Referring to the drawings by numerals, 1 designates an oven of theso-called be e hive type having an upper chargin -open- 'ing 2. Thecoalsslack as it is fed iilto'the even through the. o ening 2- tends tothe formation of a conica body, and it is the purpose of the presentinvention to expeditiously- 4 change such formation to obtain a leveledmass of slack-and one which is tamped to" f the desired degreeof'compactne's's. To this end there is employed means, including adevice'operatinginit e manner hereinafter describedr -to radually leveland temp the slack-body, t e actions of the device being at all timesunder complete control of the operator.

In its preferred form the appliance consists 5 of a ram having'memberscapable of being ,folded and extended and connected to be vibrated froma suitable source of power. All of the arts of the appliance aresupported on a'wli and out of operative position over the oveneeledcarriage 3, traveling on rails i. to bring the leveling and tampingdevice into opening 2. Vertically mounted in the car- 'riage is a shaft5, having a pointed lower endand a threaded portion 6 betweenunthreadend portions 7 The upper end portion of the shaft is slidable inan opening in a bevsled gear-wheel 9, mounted horizontally in thecarriage-heme and rotated by a beveled pinion 10 on a counter-shaft 11.12 is an engine, the drive-shaft of which is connected leys, as shown."The upper portion 7 of the shaft 5 is provided with a feather 13,whereby said shaft is rotated with the gear-wheel 9.

l The shaft and parts carried thereby are lowered and raised into andout of operative position by a rope or cable 14, attached to a sheave15, mounted on the top of a derrick 16 erected on the carriage. In saidvertical movements the shaft slides freely in the gearwheel opening,- aswill be understood. Loosely encircling the shaft 5 is a sleeve 17,having at its u per end a collar .18, provided with an annu er groove 19for a purpose ower end of the sleeve is a collar 20, having ing thethreaded ortion 6 of'the s eft. arm, to be rea ily connected anddisconnected when required, is formed of two similar members pivotallyconnected to ether at bolt .28. "When in osition, the arm 25 is invented from turning by a stationary guiderod 29, passing through anopening 30 between the arm members,

with the arms 23 folded thereagainst, is

with the center of the oven-opening, and by slackingthe-rope or cable 14is lowered into oppositely-projecting ears 21,-to each of' In operationthelower end of the shaft 5,.

with the countenshaft lihy -a'beltand pulthe upper end of the shaft andpassed around resently to be explained. Fixed on the To obtain sucharm:25 having a threaded openin 26 engag one end by a link 27 and detacha lyconnected at the oppesiteend by a nut-equipped engagement with t ecollar 18 and is pres.

, leveled, as im icated by the dotted line 31 in Fig. 1..

The tamping action follows the levcling action. above described. Afterthe operation of the parts to obtain the limit of unfolding movement ofthe arms 23 the sleeve and shaft are locked together by tightening ascrew 32, carried by thesleeve against tie shaft, or, if preferred, bylocking the collar 18 and arm 25'together, this being accomplished bybringing a hook 33, pivoted on the collar, into engagement with a pin 34on the arm 25.

The means for obtaining the tamping movement' of the arms consists of arod 35, ver tically reciprocable in guides 36 and receiving motionfrom'the cross-head or eccentric of the engine through an arm 37,adjnstably connected through. the medium of lock-nuts 38 39 with theupper end of the rod. The rod has at its lower end an arm 40, extendingtherefrom at a right angle and having a curved end 41, ada ted as thearm is swung into place to enter t e groove 19 in the collar 18 and beheld therein by the hook 33, which drops in front of said end. YVith theparts in this position the shaft 5 is coupled to the en- .gine, and thelatter being set in motion the shaft 5 and arms are both rotated andvibrated and uniform tamping of the leveled material is obtained. Tofold the arms 23 against the shaft end 8, the book 33 is caused toengage the pin 34 on the arm 25,"and the shaft being reversely rotatedthe sleeve is.

elevated and the arms brought into folded position,

tion to be with awn and transferred to another oven for the nextoperation.
